Overview

The Shape BASEPLATE kit is purpose-designed for cinematographers who need to take the Canon C500 Mark II or C300 Mark III from a cinema-body to a fully capable production rig. Whether you're building for shoulder-mount documentary work, narrative production, or interview setups where precise focus pulls and controlled flares matter, this kit provides the structural foundation and the key functional tools in a single purchase. The form-fitted cage means the camera sits correctly from the first bolt — no shimming, no improvising — and the alignment to the C500 Mark II's optical center makes shoulder balance feel natural rather than front-heavy.

The construction is CNC-machined aluminum throughout, which keeps tolerances tight even after repeated assembly cycles on location. The Arri rosette mounts on the cage and baseplate are load-bearing, designed for the kind of daily handle abuse that production work demands. The modular architecture is genuinely useful in practice — you can strip back to cage-only for gimbal work, build up to full shoulder configuration for run-and-gun, or configure for sticks with the tripod-ready baseplate. The included Follow Focus Pro engages cleanly on 15mm rods, and the 4x5.6 matte box handles standard filter sets for controlled shooting environments.

Frequently Asked Questions

It's purpose-built — the cage is form-fitted to the C500 Mark II and C300 Mark III body, with the shoulder baseplate aligned to the camera's optical center for balanced shoulder-mount operation.
The system runs on 15mm rods, the industry standard for cinema-style rigs. This means your existing 15mm follow focus units, matte boxes, and lens supports will drop straight in alongside the included components.
Yes — the modular design lets you use the cage independently with just the top handle and selected accessories, keeping weight down for handheld documentary work without dismantling the whole assembly.
The shoulder baseplate includes standard tripod attachment points and Arri rosettes, so you can transition between shoulder and sticks quickly without re-rigging the camera body.
Shape's Follow Focus Pro is compatible with standard 15mm rod setups and works with both cinema lenses (0.8 mod gear) and adapted DSLR glass — check your specific lens gear pitch before assuming direct engagement.
